SPINNING RING ANR TRAVELER THEREFOR Filed April 10, 1937 Patented Oct. 4, 1938 UNITED STATES SPINNING RING AND TRAVELER THEREFOR Charles Fillinger, Buffalo, N. Y., assignor to Herr Manufacturing Company, Inc., Buffalo, N. Y., a corporation of New York Application April 10, 1937, Serial No. 136,162

10 Claims.

This invention relates generally to certain new and useful improvements in the spinning art but more particularly to the spinning rings and bar travelers employed in connection with spinning machines.

I One of its chief objects is to so design and construct the ring and traveler as to effectually control and guide the traveler in a true and uniform path to maintain an even and constant thread-tension, and to provide for a downward and outward thrust or pressure of the traveler against the ring to counteract any tendency of the thread to exert an upward pull or thrust on the traveler during the spinning operation.

Another object of the invention is to provide a ring and traveler construction whereby chattering of the traveler on the ring is eliminated and Wear of the parts is reduced to a minimum. Other features of the invention reside in the construction and arrangement of parts hereinafter described and particularly pointed out in the appended claims.

In the accompanying drawing:- Figure 1 is a side elevation of the spinning ring and traveler embodying my invention, the same being shown associated with the, traverse bar and bobbin. 'Figure 2 is atop plan view of the ring and traveler. Figure 3 is an enlarged cross section taken on line 3-3, Figure 2. Figure 4 is a side view ofthe traveler depicted in the previous figures. Figure 5 is a fragmentary cross section showing a modified form of my invention. Figures 6 and '7 are side and perspective views, respectively, showing modifications of the 35 traveler.

Similar characters of reference indicate corresponding parts throughout the several views.

In spinning machines of the character to which my invention is particularly applicable, the

40 threads are delivered by feed-rolls (not shown) to a take-up spool II] and traversing the same is the usual vertically-reciprocating bar ll. Mounted on this bar surrounding the take-up spool is a supporting member or holder l2 of 45 substantially ring-like form and which is alined with an opening l3 formed in the bar. Applied to this holder is the spinning or traverse ring l4 adapted to be in the holder by means of a clamping member which may be in the form of a split ring l8 detachably fitted within the holder-flange [6 in bearing contact with the top side of the contig-. uousportion of the ring. The ring l4 and traveler l5 are preferably so designed as to have a tendency to impart a downward and outward movement of the traveler relative to the ring, whereby the pressure of the traveler on the ring is from the top down and. 10 from the inside out with the result that chattering and undue wear of the parts is reduced to a minimum and, further, any tendency of the thread to pull upwardly on the traveler during the spinning operations is effectually counteracted by the aforesaid relative disposition of the ring and traveler. To this end, the spinning ring [-1 is preferably of the cross section shown in Figure 3, wherein the inner bearing surface I9 thereof is flared downwardly and outwardly or ,frusto-conical-in shape, while the top bearing face 20 of the ring is flat and in a plane at right angles to the axis of the ring. The upper inside portion of the ring may be beveled or'fiared out-' wardly, as indicated at 2|. The traveler I5 is made from a single piece of wire and is of substantially the shape shown in Figures 3 and 4, the same including an outwardly-inclined bearing leg 22 which bears against the companion ,inclined bearing wall IQ of the ring, and a horizontal bearing bar 23 which bears-upon the top face 20 of the ring, the inclined traveler leg being disposed at a more or less acute angle to the top bearing bar. The traveler leg 22 terminates at its lower end in a book 24 while the top bar 20 terminates in a downwardly and outwardly-bent lug 25 which embraces the adjoining upward portion of the spinning ring. The hooked end 24 of the traveler is free to enter a downwardlympening recess or annular groove 26 formed in the bottom of the ring I4. As shown in Figure 3, the thread engages that portion or loop 21 of the traveler formed at the junction of the traveler leg 22 and bar 23, and in the normal position of the traveler on the ring this 45, thread-engaging portion of the traveler subtends the upper tapered wall 2| of the ring, thereby providing a clearance or space between these parts for the unobstructed travel of the thread By this construction, the traveler bears firmly with its leg 22 and bar 23 against the companion inclined andhorizontal bearing faces Iii-and 20 of the ring, respectively, which permits the hooked end of the traveler to float or travel'out of contact with the ring to prevent chattering of 5 5- the traveler. Furthermore, during the spinning of the traveler about the ring, the pressure exerted thereon, due to centrifugal force, tends to urge the traveler downwardly and outwardly against the respective ring-bearing surfaces, and this resulting force on the traveler effectually counteracts any tendency of the thread to pull upwardly on the traveler.

In the modified form of ring and traveler shown in Figure 5, the ring 28 is substantially the same as that previously described, with the exception that the top of the ring is of substantially invertedV-shape in cross section and the traveler is shaped to provide a downwardly and outwardly-inclined bearing leg 29 and an upwardly and outwardly-inclined bearing bar 30 which bears against the inner inclined bearing wall 3| formed at the upper end of the ring. Disposed at the junction'between the leg 29 and the bar 30 is a thread-engaging loop 32. As with the previously described construction, this modified form of my invention performs those same results of creating a downward and outward thrust of the traveler to prevent chattering and provide an even bearing for the traveler at all times.

In the modified form of traveler shown in Figure 6, the disposition of its bearing members is substantially the same as that depicted in Figure 5 with the exception that the thread-engaging loop 33 is shaped by bending the wire upon itself in the form of an eye. The modified form of the traveler disclosed in Figure '7 has its loop 34 disposed in a plane at right angles to the plane of the loops depicted in conjunction with the previously described travelers.
